Actor and Mitt Romney supporter Clint Eastwood has signed his name to an amicus brief asking the Supreme Court to recognize the constitutional right of same-sex couples to marry. Eastwood joins more than 100 prominent and top-level Republicans and conservatives signing this brief, including Meg Whitman, former Massachusetts Governor William F. Weld, former Governor of New Jersey and EPA Administrator Christine Todd Whitman, Ronald Reagan’s Director, Office of Management and Budget, David Stockman, and many others.

Breitbart, which says it “learned exclusively” about Eastwood joining the list of prominent Republicans, calls the elected officials and political luminaries “activists.”

Eastwood’s joining the amicus brief should come as no surprise. Despite his support of Mitt Romney, Eastwood supports same-sex marriage, is pro-choice, and anti-war.

Clint Eastwood last year came out in support of same-sex marriage — an institution the approved GOP platform states is “an assault on the foundations of our society.”

“These people who are making a big deal out of gay marriage?” Eastwood told GQ Magazine. “I don’t give a fuck about who wants to get married to anybody else! Why not?! We’re making a big deal out of things we shouldn’t be making a deal out of.”
